Glenn Herbert Gould (guːld; né Gold; 25 September 1932 - 4 October 1982) was a Canadian classical pianist. He was among the most famous and celebrated pianists of the 20th century, and was renowned as an interpreter of the keyboard works of Johann Sebastian Bach. Gould's playing was distinguished by remarkable technical proficiency and a capacity to articulate the contrapuntal texture of Bach's music.
Gould rejected most of the Romantic piano literature by Chopin, Liszt, Rachmaninoff, and others, in favour of Bach and Beethoven mainly, along with some late-Romantic and modernist composers. Gould also recorded works by Mozart, Haydn, Scriabin, and Brahms; pre-Baroque composers such as Jan Pieterszoon Sweelinck, William Byrd, and Orlando Gibbons; and 20th-century composers including Paul Hindemith, Arnold Schoenberg, and Richard Strauss.
Gould was also a writer and broadcaster, and dabbled in composing and conducting. He produced television about classical music, in which he would speak and perform, or interact with an interviewer in a scripted manner. He made three musique concrète radio documentaries, collectively the Solitude Trilogy, about isolated areas of Canada. He was a prolific contributor to music journals, in which he discussed music theory and outlined his musical philosophy. Gould was known for his eccentricities, from his unorthodox musical interpretations and mannerisms at the keyboard to aspects of his lifestyle and behaviour. He disliked public performance, and stopped giving concerts at age 31 to concentrate on studio recording and media.
Glenn Herbert Gould was born at home in Toronto, on 25 September 1932, the only child of Russell Herbert Gold (1901–1996) and Florence Emma Gold (née Greig; 1891–1975), Presbyterians of Scottish, English, and Norwegian ancestry. The family's surname was changed to Gould informally around 1939 to avoid being mistaken for Jewish, given the prevailing anti-Semitism of pre-war Toronto.
